Just a slightly modified version of the showroom made by the_meco. I hid that thing which produces reflections (using the same trick I used for Studio Concrete) and fixed compatibility with AC 1.8.
By the way, since version 0.7.556 Content Manager can fix that showroom to be 1.8-compatible automatically.
Can’t start Custom Showroom:
